Crashplan est un outil de sauvegarde disponible sur www.crashplan.com.

Ses avantages sont :

• disponible sur de nombreux OS dont linux
• de nombreuses fonctions dont la compression et la déduplication, en particulier pour des faibles débits (ADSL)
• la possibilité de souscrire à un stockage en ligne (cloud) pour un très faible coût (illimité pour 3$/mois)

A noter que pour les utilisateurs payants, la version Crashplan+ apporte plus de flexibilité.

Attention, crashplan utilise java et consomme une quantité de mémoire importante, je conseille de disposer d'au moins de 512Mo de RAM.

Installation sous linux du client crashplan en version 3.

Crasplan suggère une augmentation du nombre de fichiers surveillé, avec la valeur par défaut de Debian (8192), le message suivant apparait à l'installation :

Your Linux system is currently configured to watch 8192 files in real time.
We recommend using a larger value; see the CrashPlan support site for details

Il est possible d'obtenir la valeur actuelle avec la commande :

~# cat /proc/sys/fs/inotify/max_user_watches
8192
~#

Pour modifier cette valeur au démarrage, ajouter le texte suivant à la fin de /etc/sysctl.conf :

# for CrashPlan http://support.crashplan.com/doku.php/client/troubleshooting/real-time?s[]=8192
fs.inotify.max_user_watches=1048576  

Après redémarrage :

~# cat /proc/sys/fs/inotify/max_user_watches
1048576
~#

L'accès à la GUI peut se faire à distance lorsque la machine ne dispose pas d’environnement graphique.
Pour cela il faut configurer une redirection de port dans votre client SSH.

L'idée est la suivante :
La GUI se connecte sur le port 4200 de la machine client ⇒ le client SSH fait la liaison entre le port 4200 local et le port 4243 sur le serveur distant ⇒ le service crashplan écoute sur le port 4243 sur le serveur distant

Les configurations à réaliser sont :

• configurer le client SSH ainsi :

• Modifier la configuration de la GUI dans C:\Program Files\CrashPlan\conf\ui.properties, modifier l'option suivante :

servicePort=4200
